    Default question about arrays; something simple

    I am just curious what does int maxC = C[0]; mean. Why do I put C[0]; instead of int maxC = 0;

    heres the code

    public static void main...........

    int []C = {2,4,543,2};
    int maxC = C[0];
    for (int i = 0; i<C.length;i++){
    maxC = C[i];
    }

    what does int maxC = C[0]; mean
    int maxC <<< Defines an int variable named MaxC
    = <<< assigns value to right to the variable on the left
    C << name of an array
    [0] << get the element at location 0 in the array
    If you don't understand my answer, don't ignore it, ask a question.

    so, int maxC = C[0] is initializing the first element in the array?

    No, it's initializing maxC to whatever is in the first element of the array. I suggest you step through your code with a debugger, or at least add some print statements, to make it more obvious what's going on in each step.

    yeah thats what I meant lol. I just wrote it quick without more details, but thats what I meant; that C[0] is ini. maxC to whatever the first element is in the array such as

    int []A = {1,2,3,4,5};
    maxA = A[0] --> it is starting off at 1 right?

    and thanks for your help guys i appreciate it! I am just coding for fun right now!

    What happened when you tested that assumption with a print statement?

    well, when I printed it, it gave me the right answer I was looking for lol. It found the largest number I was looking for.
    Do you guys know a good website with actual problems to practice? Like "create a method using an array to find the median of numbers, multiplying each blah blah. stuff like that
